Abstract
The change in electrical resistance of copper fiber and powder compacts upo n heating from room to the sintering temperature was studied It was found t hat different regimes of heating in vacuum did not affect the temperature d ependence of electrical resistance. A relationship between electrical condu ctivity and the relative size of interparticle contacts was derived for a m odel fiber body. This was in good agreement with data on the tensile streng th of real fiber materials.
